ATTACHMENT FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 665,840, dated January8, 1901.

Application filed May 29, 1900. Serial No. 18,361. (No model.)

To all whmn it may concern:

Be it known that I, HOWARD SALMON, a citizen of the United States,residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented a new and useful Improvement in Attachmentsfor Printing-Presses, which improvement is fully set forth in thespecification and accompanying drawings.

My invention consists of an improvement in an attachment forprinting-presses wherein I provide suction devices operated with respectto the printing-rolls, having cut-oif valves for said suction devicesand means for actuating said valves and suction devices so that thepaper is properly presented to the printing-rolls.

It also consists of novel means for raising the bed as the material isremoved therefrom.

It also consists of a novel construction of feeding device adapted tocoact with the suction devices.

It also consists of a novel mechanism for creating and controlling thesuction at the proper intervals.

It also consists of novel details of construction, as will behereinafter fully described, and particularly pointed out in the claims.

Figure 1 represents a side elevation of a feeding device forprinting-presses embodying my invention, certain portions thereof beingshown in section. Fig. 2 is a section of Fig. 1, taken on the line so asof Fig. 1, looking in the direction of the arrows. 3 represents asection on line z 2, Fig. 1. Figs. 4 and 5 represent sections on lines yy, Fig. 1, showing the different positions ofa portion of the mechanismfor feeding the material after the same has been printed. Fig. 6represents a front elevation of a portion of the feeding mechanism seenat the upper left-hand portion of Fig. 1. Fig. 7 represents, on anenlarged scale, a side elevation of a portion of feeding mechanism, tobe hereinafter referred to. Fig. 8 represents a side elevation, partlybroken away, of a portion of the suction mechanism. Fig. 9 represents aside elevation of certain detached portions of the device.

Similar numerals of reference corresponding parts in the figures.

indicate Fig.

Referring to the drawings, 1 designates ,the main shaft, which ismounted in suitable bearings in the framework or housing 2 and isactuated in any suitable manner, said shaft carrying the gear 3, whichmeshes with the gear 4, mounted on the shaft 5, which carries theprinting-roll 6, which is located above the roll 7, mounted on the shaft1.

8 designates an eccentric mounted on the shaft 1 and carrying theeccentric-strap 9, wherefrom connection is made by the eccentric-rod 10and piston-rod 11 to the piston 12 in the cylinder 13, said piston-rod11 being guided in the ways 14. l

l5 designates an eccentric mounted on the shaft 1 and having theeccentric-strap 16, which has extending therefrom the rod 17, one end ofwhich engages the slotted end of the lever 18, which is loose on theshaft 19, which latter carries the pinion 20, which meshes with the rack21, guided in the ways 22;

23 designates a ratchet-wheel mounted fast on the shaft 19 and adaptedto be actuated by the pawl 24, carried by the arm 18, said pawl beingheld in position by the spring 25, it being apparent that saidratchet-wheel is prevented from improper motion by the check pawl or dog26.

27 designates a bed or support for the paper or material 28, which isadapted to be fed through the rolls 6 and 7. The feeding of the paper iseffected by the suction through the nozzles 29, connected to the pipes30, which latter are opened and closed at the proper intervals by thevalves 31, whose stems 32 carry the arms 33, on which are mounted therollers 34.

44 designates flexible connections to the pipe 45, which leads from thereservoir 46, which communicates with the valve 47 by the pipe 48, saidvalve being connected with the cylinder 13, which has the valveconnection 49, leading therefrom.

5O designates a roll mounted at the discharge side of the roll 7 (seeFig. 1) and adapted to propel and direct the printed sheet 51 to itsproper place upon the delivery-bed 52.

The sheet 51 is propelled by the pusher 53, which is actuated by the arm54, which is connected to the slotted arm 55, secured to the shaft 57,journaled in the hanger 58, so as to be operated by the slotted arm 56,which is engaged by the lower end of the rod 59, attached to theeccentric-strap 60, which is actuated by the eccentric 61.

62 designates a recess in each of the sides 63, adjacent which issecured the spring 64, the latter having the upturned portion 65.

35 designates cams firmly secured to the shaft 5 and adapted to impart arocking motion to the lever 36, whose members 37 are fulcrumed, as at38, in the frame 2.

39 designates stationary cams secured to the frame 2 and provided withWorking faces 40, on which the rollers 34 are adapted to travel when thevalves 31 are raised and lowered in order to open and close the same.The valves 31 are provided with tongues 41, which travel in grooves 42in the frame 1, so as to cause said valves to be properly guided intheir up and down movements.

43 designates arms journaled, as at 66, in the frame 2 and adapted to berocked on said journals by the cams 67 and springs 68.

The lower portions of the arms 43 engage a cross-bar 69, guided in ways70 in the frame 2, so as to impart a reciprocating motion to saidcross-bar. (See more particularly Fig. 6.)

The cross-bar 69 has fitted thereon in any suitable manner the grippers71, which may be moved either nearer to or farther from each otheraccording to the width of the article to be printed. The grippers 71 arekept normally closed by the springs 72.

73 designates triggers pivoted to a cross-bar 74, secured to the frame2, said triggers being adapted to be moved either toward or from eachother according to the Width of the article to be printed.

The grippers 7 l are formed with heel portions 75, adapted to work inconjunction with the triggers 73, so as to cause said grippers 71 to beopened and closed at certain intervals.

When the grippers 71 have reached their farthermost position To theright, (see Fig. 1,) the heel portions 75 thereof are depressed by thecam 76, thus causing the grippers to open and release the articlepreviously held by them.

The articles fed to the delivery-bed 52 are retained in position thereonby the weighted fingers 77, which bear against said article and causethe same to abut against the upturned portions 65, thereby causing thearticles to fit snugly within the box formed by the delivery-bed 52 andsides 63.

The bed 52 may be raised or lowered so as to be properly adjusted tovarious dimensions of articles fed thereto, it being apparent that whenthe thumb-nuts 78 are slackened the bed 52 may be either raised orlowered.

The sides 63 and 79 of the beds 27 and 52, respectively, are adjustablerelatively to the width of the article to be printed.

80 designates a lever loosely fitted on the shaft 19 and provided withan arm 81, adapted to contact at certain times with the under side ofthe projecting portion 82 of the dog 24, so as to remove the latter fromengagement with the teeth of the ratchet-wheel 23. The lever 80 is alsoprovided with an upturned portion 83, adapted to be brought at certaintimes in contact with the heel 84 of the checkpawl 26, so as to removethe latter from engagement with the teeth of the ratchetwheel 23.

When the wheel 80 is in the position seen in full lines in Fig. 9, thedog 24 and checkpawl 26 are removed from engagement with the teeth ofthe ratchet-wheel 23, thereby permitting the bed 27 to be lowered whenso desired. When the lever 80 is released, it turns on the shaft 19 inthe direction indicated by the arrow in Fig. 9 and moves into theposition seen in dot-ted lines in said figure, it being noted that thedog 24 and check-pawl 26 are then permitted to again engage the teeth ofthe ratchet-wheel 23, as is evident.

The lever 80 is omitted in Fig. 1 for clearness of illustration ofcertain of the parts in said figure; likewise the projection 82, formingpart of the dog 24.

The operation is as follows: The paper to be printed is placed upon thebed orsupport 27 and appears in stacks at 28, the height of said bedhaving been adjusted, depending upon the amount of paper to be printed.The machine is now started, power being applied thereto through thepulleys, and the shaft 1 is caused to operate. This gives motion to theeccentric and eccentric-strap 9, causing the piston 12 to operate andcreating a suction in the reservoir 46, which communicates withthenozzles 29 by a suitable pipe provided with a branch to both nozzles.The shaft 5 meanwhile has been operated, which imparts motion to theearns 35, which in revolving impart motion to the lever 36 and lower thesame, carrying with it the nozzles 29, which are thus brought in closeproximity to the paper. In its descent the nozzles carry with it therollers 34, which will move on the faces 40 so as to assume the positionseen in Fig. 8, at which time the valves 31 are open, and the suctioncaused by the operation of the machine will cause a sheet of the paper28 to be raised with the nozzles, which it now does as the cams 35continue to revolve and strike the end 37 of the lever 36. As the shaft1 revolves it carries with it the eccentric l5 and the strap 16, whichoperates the rod 17, journaled in the slotted lever 18, which carriesthe pinion 20 and the pawl 24, which engages with the ratchet-wheel 23,mounted on the shaft 19 and carryinga pinion 20, which turns and raisesthe rack 21 and with it the bed 27, thus moving the paper adistanceequal to one sheet thereof. The paper which has been raised by thenozzles 29 is now engaged by the grippers 71, which have been movedforward with the arms 43, actuated by suitable cams, said grippersdelivering the paper between the rolls 6 and 7, where the impression ismade, and from thence the paper is passed between the roll 7 to the roll50 and discharged, as shown at 51 in Fig. l, and is propelled by thepusher 53 out of the path of the next succeeding sheet, the springs 64preventing the return of the paper. The parts then assume their originalpositions ready for the next sheet.

It will of course be apparent that various changes may be made in thedetails of construction without departing from the spirit ofmyinvention, and I therefore do not desire to be limited in every instanceto the exact construction as herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
